Apache Tez for Hadoop >= 2.0

The Apache Tez project is aimed at building an application framework which allows for a complex directed-acyclic-graph of tasks for processing data. It is currently built atop Apache Hadoop YARN. The 2 main design themes for Tez are:

• Empowering end users by:

• Expressive dataflow definition APIs
• Flexible Input-Processor-Output runtime model
• Data type agnostic
• Simplifying deployment

• Execution Performance
  • Performance gains over Map Reduce
  • Optimal resource management
  • Plan reconfiguration at runtime
  • Dynamic physical data flow decisions
